COMPUTING-SCALE.

Speccaton of Letters Patent.

Patented May 7, 1907.

Application filed October 3,1906. Serial Noi 337,300.

To all whom t may concern:

Be it known that 1, FREDRIGK E. GAB- BERT, a citizen of the UnitedStates, residing at Kelly, in the county of Nemaha and State of Kansas,have invented certain new and useful Improvements in Computing-Scales,of which the following is a specification.

My invention relates to'computing scales and more especially to thattype of scale which shows the weight of the commodity and the moneyvalue of the same, and my object is to produce a scale of this characterof simple, strong, durable and cheap construction.

A further object is to produce a scale of this character which will alsoshow the net weight of cream and the money value of the butter fatcontained in "such cream.

Vith these objects in view and others as hereinafter appear, theinvention consists in certain novel and peculiar features ofconstruction and organization as hereinafter described and claimed; andin order that it may be fu'lly understood reference is to be had to theaccompanying drawings, in which- Figure 1, represents a scale partly inside elevation and partly in central vertical section, embodying myinvention. Fig. 2, is a plan view of a portion of the scale. Fig. 3, isa view partly in elevation and partly in central vertical section of aportion of the scale. Fig. 1, is a vertical section on the line IV-IV ofFig. 1. Fig. 5, is a full-sized view of a portion of the scale. Fig. 6,is a vertical section taken on the dotted line VIV1 of Fig. 5. Fig. 7,is a vertical section on the line VII of Fig. 6. Fig. S, is a face viewof a portion of the computing chart.

In the said drawings, 1 indicates a ortion of the frame and 2 a partofthe box o a scale of any suitable type. 3 indicates the base of theupper portion of the scale resting on frame 1, provided with alongitudinal slot 4 through which the securing bolt 5 of the frameextends. 6 indicates standards at one end of the base, and 7 a guidestandard at the opposite end of said base.

8 indicates the tare beam provided with an upwardly projecting arm '9,equipped with outwardly projecting knife bearings 10, engaging bearingcavities 11 in the upper ends of standards 6.

12 indicates arms projecting upwardly from the ends of the tare beam, 13the usual threaded rod connecting one of said arms with arm 9 andequipped with an adjustable poise 14 known as the scoop poise.

15 is an arm projecting from the contiguous arm 12 through the standard7 and pivotally suspended from arm 15 is the weightcarrying rod 16. rlhearm 12 from which arm 15 projects is provided with a horizontal aperture17 in longitudinal alinement with the cavity 18 in the other arm 12.

19 indicates a rectangular frame provided centrally of one end bar witha pin 20 to fi nd a journal in aperture 17, the other end bar of said.Arame being provided wi th a pin 21 to nd a journal in the cavity 1S. lnsecuring the frame in position pin 20 is first slipped into the.aperture 17 until pin 21 is in alinement with aperture 18 and then themovement of the frame is reversed to effect engagement between thelast-named pin and cavity 1S. To enable the operator to so dispose theframe, the length of the lat ter is less than the distance between theupper ends of arms 12 and to prevent accidental dislocation of pin 21from cavity 1S, eXp ansive spring 22 is mounted on pin 20 and bears atits opposite ends against the contiguous arin 12 and the base of asleeve 23 rigid with the frame and pin 20 and surroundinf1-` the spring22- to centralize it with respect to said pin. The frame as thusarranged is reversible, that is to say it is rotatable so that eitherface can be disposed toward the operator. At opposite sides said frameis provided with a scale 24- representative of pounds and fractionsthereof, said graduations being so disposed that they'appear at the topof the frame when its corresponding side faces toward the salesman.

5 indicates a chart containing vertical columns of figures, each columncontaining at regular intervals figures in black or heavy type, suchfigures of the various columns being horizontally alined. There is onecolumn for each pound mark of the graduations 24 and the black typeligures of any column vertically alined with any particular pound markof said graduations represents the value of the number of poundsrepresented by said pound mark at different prices per pound.

The black or heavy faced iigures of each column also represent thenumber of pounds of butter fat in a quantity of cream, the weight ofwhich is indicated by the pound mark on said graduations in verticalalinement with the particular number, and the light faced figuresrepresent the money value of the number of pounds of butter vtatrepresented by the first black faced figures next above, at indicatedprices per pound as hereinafter explained.

26 indicates a poise for adjustment upon frame 19 and of double faceconstruction so as to operate in conjunction with either of thegraduations 24. rl`he poise consists of a rectangular frame Yfittingslidingly ou frame .19 an d provided at one end of each side with anopening 27 to expose a portion of the graduation 2i and with a finger 28to point to the pound marks on such graduations as they are successivelyencountered. The poise is likewise provided with a vertical slot 29through which may be observed one of the vertical columns of figures ofthe chart. At one side of the slot the poise is provided with large'figures at regular intervals, the figures shown being 25 to 37inclusive, these `hgures representing the prices per pound of acommodity if the scale is to be used by a groceryman or for weighingordinary commodities. .lf the scale is to be used by creameries thesefigures indicate butter fat tests, that is different percentages ofbutter fat in a pound of cream.. The spaces contiguous to the largenumbers are subdivided equally into seven spaces, the top-most of eachseries of seven spaces being horizontally alined with the horizontalseries of black or heavy ligures, the remaining spaces contiguous tosaid large figures of said poise are numbered consecutively, the figuresshown being 20, 21, 22,7 23, 24 and 25, these figures representingdifferent prices per pound at which the butter fat may be sold. Thesepoise figures are horizontally alined with light face figures of thecolumns of the chart, as shown clearly in Fig. 5.

The construction of the poise described is duplicated at each side withthe exception that the large figures will of course be different theymay run from 25 downward or from I upward as creameries will seldomaccept cream which tests less than 25% butter fat.

To avoid the possibilityT of making a mistake in reading from the chartand to facilitate such reading the poise 26 is equipped at each sidewith a friction slide, said slide consisting of a rectangular plate 30provided with openings 31 and with tongues 32 at its upper and lowerends which project into slot 29 of the poise to insure verticalreciprocation of the slide.

33 indicates an arc shaped spring of greater width than aperture 31 andthe slot 29 and notched at its ends as at 34 in order that such reducedportions may extend through apertures 31 and slot 29, the body portionof the spring bearing against the face of the slide and the ends of thespring beyond said notches bearing against the inner faces of thecontiguous side of the poise.

35 indicates a screw carried by and bearing a threaded relation to thespring and bearing at its inner end against the slide. By adjusting thescrew the spring is caused to clamp the slide against and upon the poisewith sufficient pressure to hold the former at any desired. point ofadjustment on the latter.

In the use of the scale as an ordinary price scale when no receptacle isplaced upon the scale platform, the poise 36 of the tare beam stands at0 and is not disturbed, the poise 26 is adjusted on the frame 19 untilthe commodity is balanced when its finger 28 indicates the number ofpounds. Assuming that the weight is 'fifty pounds and that the price ofthe connnodity is twenty six cents per pound, the slide 3G is .movedupward 'until its upper edge registers with the black or heavy facedligure showing through the slot opposite the space represented by thelarge 'ligure 26 on the poise, which figure is $13.00.

lf the price per pound corresponds to either of the four lower figureson the poise, the lower edge of the slide can be used as a gage indetermining the value of the comi nodity weighed, as by such use lessadjustment of the slide is necessary.

lf it be desired to ascertain themoney value of the butter fat containedin a quantity of cream, the can containing the cream which is to beweighed, is 'first weighed by means of the poise 36, though in practicethe weight of such can is known. and thus renders unnecessary suchseparate weighing operation.

Assuming that the weight is 15 lbs. the poise 36 is set at 15 as in Fig.1, and then the net weight of the cream is ascertained by adjusting thepoise 26 on frame 19. Assuming that the net weight of the cream is`fifty pounds, as indicated in l." ig. 5, and that the cream tests 26%(the test being known before the weighing operation takes place) theslide is moved until its upper edge registers with the division marknext below the large or test ligure 26. It will thus be seen that fiftypounds of cream testing 26% contains thirteen pounds of butter fat, thisbeing ascertained by reference to the heavy faced type which isdisclosed on the chart through the slot 29 and opposite the spacerepresented by said ligure 26. Now if butter fat is selling at 21e perpound, the slide is moved upward until its upper edge registers with thegure 21 in said space, the 'ligure showing through the slot 29 inhorizontal alineinent with said figure 21 representing the money value,viz 2.73 for thirteen pounds of butter fat at 21e per pound.

It will thus be seen that by means of this computing scale the value ofthe butter fat IOO in any given quantity of cream at a given test canvbeascertained easily and expeditiously.

From the above description it will be apparent that I have produced acomputing scale possessing the desirable features enumerated and whichobviously may be modified in various particulars without departing fromthe spirit and scope of the appended claims.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent, is
